It boasts both elasticity and structural rigidity in tactile feel. It is compact in size. Each seal can be precisely embedded into the mounting groove of small valves.As a core sealing component for micro fluid control systems, it complies with the stringent standards of Mini Sealed Valve and Sealed Fluid Direction Control Valve. It is fully compatible with the application requirements of Check and Non-Return Valves and One-Way Flow Valves.
Product Features
1. Functions
1)Leak Prevention for Mini ValvesIt serves as a core sealing component of small valves. It fills the mating gaps between valve cores and seats. It precisely blocks the leakage of fluids (liquids and gases). It maintains the sealing reliability of valves. It avoids medium loss and equipment malfunctions caused by leakage. This sealing performance meets the rigorous demands of Sealed Diaphragm Pump and Sealed Fluid Transfer Pump accessory standards for micro fluid systems.
2)Adaptation to Valve Assembly and PositioningThe base structure with positioning teeth can be precisely embedded into the mounting position of mini valves. It prevents the seal from shifting during valve opening and closing. It ensures continuous sealing performance.
3)Buffering Impacts During Valve OperationIt leverages the elasticity of EPDM. It cushions the component impact generated when mini valves are opened and closed. It reduces mechanical wear between the seal and valve core. It extends the service life of valves.
2. Performance Characteristics
1)EPDM Material + 60–65° Hardness Balances Sealing Performance and DurabilityEPDM boasts excellent temperature resistance (-40℃~150℃), aging resistance and medium resistance (compatible with common fluids such as water and weak acids/alkalis). The 60–65° medium-hardness setting not only retains sufficient elasticity to fit the micro-gaps on valve sealing surfaces. It provides good deformation resistance at the same time. It avoids creep failure after long-term use. This performance advantage aligns with the technical specifications of Micro Sealed Hydraulic Pump and high-reliability micro sealing components.
2)Multi-Profile Structure Adapts to Different Mini Valve TypesThe "trapezoidal boss + positioning-tooth base" design can meet the sealing requirements of different types of mini valves such as small stop valves and one-way valves. It improves adaptation compatibility. This structural versatility complies with the matching standards of Directional Control Valves and integrated micro fluid control systems.
3)High-Precision Dimensions for Mini Valve Precision AssemblyIt is compact in size with strict tolerance control. It can perfectly match the micro sealing grooves of mini valves. It avoids poor sealing caused by dimensional deviations. It meets the precision assembly requirements of small valves.
3. Application Scenarios
1)Micro Fluid Control ValvesIt is suitable for sealing micro stop valves in laboratory precision instruments and medical equipment. It is used for leak-proof control of trace fluids such as sample liquids and reagents. It is a key component for the precision operation of Fluid Check Mechanisms in micro fluid systems.
2)Small Household Appliance ValvesIt is applicable for sealing micro valves in household appliances such as coffee machines and water dispensers. It ensures leak-proof performance in beverage delivery. It matches the assembly needs of Reverse Prevention Valves in small fluid control devices.
3)Electronic Equipment Fluid ComponentsIt is used for sealing micro water valves in electronic heat dissipation systems and mini control valves in pneumatic components. It blocks the leakage of cooling liquids and compressed air. It complies with the quality standards of Micro Sealed Hydraulic Pump auxiliary sealing parts.
4. Pain Point Solutions
1)Solving Sealing Failure of Mini ValvesOrdinary small seals have large dimensional tolerances and poor fit. They easily lead to micro valve leakage. The high-precision dimensions and medium-hardness elasticity of this seal enable reliable sealing of micro gaps. It enhances the performance of Mini Sealed Valve components in micro systems.
2)Resolving Adaptation Issues of Multiple Mini Valve TypesSeals with a single structure are difficult to adapt to different types of mini valves. The multi-profile design can cover application scenarios such as stop valves and one-way valves. It improves versatility. It meets the diverse needs of Directional Control Valves in micro fluid control.
3)Addressing Deformation Failure of Small SealsLow-hardness small seals are prone to deformation failure under pressure. High-hardness ones have insufficient fit. The 60–65° hardness balances elasticity and deformation resistance. It extends the service life of the seal. It optimizes the durability of Sealed Fluid Direction Control Valve accessory parts.
4)Solving Positioning Difficulties in Micro AssemblyMini valves have limited installation space. Seals are prone to displacement. The base structure with positioning teeth can be precisely embedded into the mounting position. It avoids sealing failure caused by assembly deviations. It fully meets the operational requirements of Fluid Check Mechanisms and Reverse Prevention Valves.
